The process by which rocks are broken down by wind and water is known as erosion. Erosion involves the removal and transport of soil and rock particles, often leading to landscape changes over time. Natural forces like rainfall, rivers, and ocean waves contribute to this process, continuously reshaping Earth’s surface. Erosion can also result from human activities such as deforestation and construction, which can accelerate the rate at which rocks and soil are worn away. Understanding erosion is essential for managing land and preventing soil degradation.
